High Quality Final Gathering for Hierarchical Monte Carlo Radiosity for General Environments

Aiming at rendering high quality images robustly for general environments with simple algorithms, we use a two-pass method that accounts for the global illumination. In this paper we present the integration of a new gathering procedure in the rendering pass, that uses the approximate results obtained by a particle tracing method, an extension of the Hierarchical Monte Carlo Radiosity (HMCR) alg...

Fast Local Approximation to Global Illumination

Interactive global illumination remains an elusive goal in rendering, as energy from every portion of the scene contributes to the final image. Integrating over a complex scene, with a polygon count in the millions or more, proves difficult even for static techniques. Interacting with such complex environments while maintaining high quality rendering generally requires recomputing the paths of ...

DIRmaps : Discretized Incident Radiance Maps for High-Quality Global Illumination Walkthroughs in Complex Environments

Realtime ray tracing and interactive global illumination have recently made significant progress, allowing for ray traced rendering quality even in highly complex scenes. Nevertheless, high-quality global illumination is currently still limited to offline computations, as existing interactive techniques are applicable only to simple scenes, BRDFs, and/or lighting conditions. For realistically c...

Fast Global Illumination Including Specular Effects

Rapidly simulating global illumination, including diffuse and glossy light transport is a very difficult problem. Finite element or radiosity approaches can achieve interactive simulations for some classes of diffuse-only scenes, but more general methods are currently too slow and too noisy for interactive use. We present a new method which seamlessly integrates particle tracing (for nondiffuse...
